'FUR-PLUCKINQ MACHINE."

SPECIFICATION forming part of Letters Patent No. 367,200, dated July 26, 1887.

Application filed April Q0, 1887. Serial No. 235,465. (No model.)

To all whom it may concern.-

Be it known that I, IsIDoR DRESDNER, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Fur-Plucking Machines; and I do hereby declare that the following is a full andexact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification, in which- Figure 1 is a central vertical section at a right angle to the axis of the plucking-roller in my improved machine, (see line as x of Fig. 2;) and Fig. 2 is a front elevation of the ma chine with the fur-supporting roller and its supporting-frame removed.

Similar letters indicate corresponding parts in both figures.

My invention is designed to facilitate the plucking of fine furs, and especially of muskrat skins, by machinery.

It consists in the combination, with an elastic roller and a series of revolving blades whose edges bear successively against said roller, of a comb having curved teeth whose convex face is brought into proximity to the roller and an adjustable supportin'gbar or friction-roller adapted to be carried into close proximity to the opposite concave face of the comb, and over which thepelt is drawn so as to carry its long hairs through the comb.

It consists, also, in devices, as hereinafter described, for clearing the rollers of fur and for adjusting the rollers and frame.

In the accompanying drawings, A represents a fixed frame constructed of the standards a a and cross-bars B and O, and which is mounted upon a suitable stand or table, D.

E is a shaftjournaled at each end in sliding boxes F F, adapted to move vertically in longitudinal slots G G, formed in the standards a a,- and H aparallel shaft mounted under the shaft E in similar boxes, 0 0, playing in the same slots G G.

I I are spiral springs interposed between each pair of journal boxes F and 0, whereby the two shafts E G are kept apart by an elastic bearing. t

J J are setscrews working through the upper cross-bar, O, of the frame against the upper journal-boxes, F F, so as to adjust them in reference to the lower boxes, 0 O, and K K or a weight as its equivalent.

are lock-nuts by which these screws are fixed I lower shaft, H, and are made to bear longitudinally against the periphery of the roller L, Fig. 1.

N is an adjustable plate or bar attached to the front of the frame A, about on a level with the lower shaft, H, by means of two screws, N N which pass through slots b b in the ends of the plate and work, respectively, into the edge of each standard a a. The slots 1) b are out transversely in the plate or bar N, so as to permit a vertical movement and adjustment of the plate upon the supporting-screws N N Set-screws 0 0, at each end of the plate, are made to work through the plate and bear against the standards a a, so as to permit of an adjustment of the plate N to and from said standards, and, in connection with the supporting screws N N, to fix it when adjusted.

A series of metallic teeth, P P P, are secured to the upper edge of the plate N, or

formed integrally therewith, to project diagonally therefrom toward the plucking-roller L and form a comb. The upper ends of the several teeth P P are bent uniformly back, as shown in Fig. 1, so as to form a longitudinal recess in the comb, which, by reason of the relative adjustment of the comb-plate N and roller L, is brought to about the level of the bottom of the roller.

A pelt-supporting roller, Q, Fig. 1, of a length corresponding with that of the comb, is supported to rotate freely in suitable hearings in the ends of two bent arms, R R, carried by a frame, S, mounted to slide freely to and from the standards of the roller-frame'A in suitable ways, T, secured to the table or stand D in front of said roller-frame. The sliding frame S is made of such length as that its front end will project beyond the front edge of the stand or table D,-as shown in Fig. 1, and it is automatically carried out away from the frame A by means of a suitable spring, S, The frame S is moved forward, as required, to bring the peltsupporting roller Q into proximity to the teeth P P ofthc comb, by thepressure ofthe operators body against the front bar of said frame S. The pelt-supporting roller Q is adjusted as to height, so as to permit it to pass into the concavity of the comb, as shown in Fig. 1, by fitting the two arms R It, which carry the roller, into vertical guide-recesses c 0, formed in the inner end of the frame S, and securing them, when adjusted vertically, by means of setscrews ff, working through longitudinal slots h 71, formed in said arms. (See Fig. 1.)

To prevent the fine hairs plucked from the fur by the radial blades M M and pluckingroller L from clogging the bearings of the roller-shaft E and the surface of the roller ilselfla flap, V, of leather or its equivalent, is made fast at the top edge of each of the upper journal-boxes, F, of the rollershaft, to depend therefrom and embrace the portion of the shaft between the roller L and its bearings, the flap being perforated to allow the roller to pass through it. The perforation is so large as to permit of a free play or vibration of the flap longitudinally along the shaft, and in the movements of the machine the automatic vibration of the flap will cause it to clear away the flying fur and hairs before they can pass into the bearings or adhere to the shaft. A third heavier flap, \V, preferably of soleleather, is secured to the upper cross-bar, G, of the frame A, and is doubled in under the bar to rest upon the surface of the rubber roller L, and by its frictional contact therewith clear its surface of the fur and hairs which may adhere thereto.

The shaft H, carrying the radial pluckingblades M M, is fitted with a pulley, H, to equalize the movements of the machine, and the shaft may be rotated by hand or by means of a motor, to which it is geared in the customary manner.

In the operation of the machine the shaft H and the radial blades M M, carried thereby, being made to revolve with a uniform motion, the pelt to be plucked is led over the roller Q with the hair side outward. The roller, with the fur doubled over itand held by the hands of the operator, is then carried forward by the pressure of the operators body against the projecting front bar of the frame S, until the fur is brought within the curved recess in the comb so that the long hairs shall project for ward between the teeth of the comb in position to be caught at their ends between the edges of the radial blades M M and the surface of the rubber roller L. As the edges of the blades bear closely against the roller, they take firm hold of these long hairs, and by the forward movement of the blades in their revolution these hairs are plucked out, the fur being protected and supported by the teeth I? l of the comb in connection with the fricti0uroller Q.

As fast as the hairs are plucked, the pelt is drawn forward over the roller Q by the operator, who meantime, by holding the ends of the skin, keeps it properly stretched thereon, and moves it back or forth, as required, the approximation of the fur to the teeth and roller being adjusted meantime by the pressure of his body against the frame S, said pressure counteracting the action of the spring Sin the opposite direction.

I claim as my invention 1. The combination, in a fur-plucking machine, of the revolving radial blades, the parallel elastic roller against which the edges of the blade strike in their revolution, the parallel adjustable bent comb, and the parallel adjustable skin-supporting roller mounted to move to and from the concave side of the comb, all substantially in the manner and for the purpose herein set forth.

The combination, with theplucking roller in a fur-plucking machine, of oscillating flaps mounted to vibrate longitudinally upon the shaft between each end of the roller and the journal-bearings, substantially in the manner and for the purpose herein set forth.

3. The combination, with the plucking-roller in a fur-plucking machine, of a flap secured to rest with its free edge upon the surface of the roller, substantially in the manner and for the purpose herein set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ISIDOR DRESDNER.
